3-138 Muhammad ibn Ali Majiluyih - may God be pleased with him - narrated that his uncle Muhammad ibn Abil-Qasim quoted Ahmad ibn Aba Abdullah al-Barqy, on the authority of his father, on the authority of Abdullah ibn al-Muqayrih, on the authority of Abil Sabah al-Kanani, on the authority of Abi Basir

that Abi Ja’far al-Baqir (MGB) said, “The following three are the hardest things to do for a believer: to be fair regarding oneself, to help others, and remember God in all circumstances. One should remember God whenever he is about to commit a sin as the Honorable the Exalted God said, ‘Those who fear God, when a thought of evil from Satan assaults them, bring God to remembrance, when lo! they see (aright)!’ .”
